We illustrate why a spacetime structure as in General Relativity is not in contradiction with a dynamical origin of gravity from a scalar field. Further, we argue that the recently discovered gapless mode of the singlet Higgs field represents the most natural dynamical agent of Newtonian gravity.

We present a setup that provides a partial UVcompletion of the ghost inflation model up to a scale which can be almost as high as the Planck mass. This is achieved by coupling the inflaton to the Lorentzviolating sector described by the Einsteinaether theory or its khronometric version. Compared to previous works on ghost inflation our setup allows to go beyond the study of small perturbations and include the background dynamics in a unified framework. In the specific regime when the...

We consider a Lorentzviolating theory of gravity where the aether vector is taken to be nondynamical. This "ponderable aether theory" is almost the same as Einsteinaether theory (where the aether vector is dynamical), but involves additional integration constants arising due to the loss of initial value constraints. One of these produces an effective energy density for the aether fluid, similar to the appearance of dark matter in projectable Ho\v{r}ava gravity and the mimetic dark...

Relativistic BoseEinstein condensates (rBECs) have recently become a wellestablished system for analogue gravity. Indeed, while such relativistic systems cannot be yet realized experimentally, they provide an interesting framework for mimicking metrics for which no analogue is yet available, so paving the way for further theoretical and numerical explorations. In this vein, we here discuss black holes in rBECs and explore how their features relate to the bulk properties of the system. We then...

The accelerating expansion of the Universe poses a major challenge to our understanding of fundamental physics. One promising avenue is to modify general relativity and obtain a new description of the gravitational force. Because gravitation dominates the other forces mostly on large scales, cosmological probes provide an ideal testing ground for theories of gravity. In this thesis, we describe two complementary approaches to the problem of testing gravity using cosmology. In the first part, we...

We propose a novel solution for the endpoint of gravitational collapse, in which spacetime ends (and is orbifolded) at a microscopic distance from black hole event horizons. This model is motivated by the emergence of singular event horizons in the gravitational aether theory, a semiclassical solution to the cosmological constant problem(s), and thus suggests a catastrophic breakdown of general relativity close to black hole event horizons. A similar picture emerges in fuzzball models of black...

Recently proposed theories based on the cosmic presence of a vectorial field are compared and contrasted. In particular the so called Einstein aether theory is discussed in parallel with a recent proposal of a strained spacetime theory (Cosmic Defect theory). We show that the latter fits reasonably well the cosmic observed data with only one, or at most two, adjustable parameters, whilst other vector theories use much more. The Newtonian limits are also compared. Finally we show that the CD...

By restricting to the level of linear perturbations around Lorentzviolating vacuum and using the superfield formalism we construct the most general action invariant under the linearized supergravity transformations. We show that, unlike its nonsupersymmetric counterpart, the...

Under broad assumptions breaking of Lorentz invariance in gravitational theories leads to tension with unitarity because it allows for processes that apparently violate the second law of thermodynamics. The crucial ingredient of this argument is the existence of black hole solutions with the interior shielded from infinity by a causal horizon. We study how the paradox can be resolved in the healthy extension of Horava gravity. To this aim we analyze classical solutions describing large black...

It is known that large scale magnetic fields could be generated if there exist cosmological vector mode perturbations in the primordial plasma. The vector mode, however, has only a decaying solution in General Relativity if the plasma consists of perfect fluids. In order...

Quantum YangMills theory can be rewritten in terms of gaugeinvariant variables: it has the form of the socalled BF gravity, with an additional `aether' term. The BF gravity based on the gauge group SU(N) is actually a theory of high spin fields (up to J=N) with high local symmetry mixing up fields with different spins  like in supergravity but without fermions. At N going to infinity one gets a theory with an infinite tower of spins related by local symmetry, similar to what one has in...

As vector field fluctuations are responsible in GEA for seeding baryonic structure formation, vector field concentrations can exist independently of baryonic matter.

This theory has a parameter range that satisfies all current weakfield tests. We find that within this range it leads to lower maximum neutron...

We investigate the case of a single vector ``aether'' field on a compact circle.

Using this procedure, the Lorentz force is no longer separate from Maxwell's equations. The Lorentz transformations are shown to be related to the convective derivative, which is introduced in the electrodynamics of moving bodies. The new formulation is in complete agreement with the actual set of Maxwell's equations for bodies at rest, the only novel feature...

The twodimensional aethersuperspace is constructed and the superfield techniques are applied to the study of dynamical generation of mass in the Lorentzviolating supersymmetric quantum electrodynamics in two dimensions of spacetime. It is shown that such model presents a dynamical generation of mass to the gauge aethersuperfield and its dispersion relation has the structure similar of the CPTeven Lorentzbreaking models.

Despite the tremendous empirical success of equivalence principle, there are several theoretical motivations for existence of a preferred reference frame (or aether) in a consistent theory of quantum gravity. However, if quantum gravity had a preferred reference frame, why would high energy processes enjoy such a high degree of Lorentz symmetry? While this is often considered as an argument against aether, here I provide three independent arguments for why perturbative unitarity (or weak...

In recent years, a number of alternative theories of gravity have been proposed as possible resolutions of certain cosmological problems or as toy models for possible but heretofore unobserved effects. However, the implications of such theories for the stability of structures such as stars have not been fully investigated. We use our "generalized variational principle", described in a previous work, to analyze the stability of static spherically symmetric solutions to spherically...

We study black hole solutions in general relativity coupled to a unit timelike vector field dubbed the "aether". To be causally isolated a black hole interior must trap matter fields as well as all aether and metric modes. The theory possesses spin0, spin1, and spin2 modes whose speeds depend on four coupling coefficients. We find that the full threeparameter family of local spherically symmetric static solutions is always regular at a metric horizon, but only a twoparameter...

We speculate that the universe may be filled with a continuum which may be called aether. Based on a spherical source and sink model of electric charges, we derive Coulomb's law of interactions between static electric charges in vacuum by methods of hydrodynamics. A reduced form of the Lorentz's force law of static electric charges is derived based on a definition of electric field.

The gravitational aether theory is a modification of general relativity that decouples vacuum energy from gravity, and thus can potentially address the cosmological constant problem. The classical theory is distinguishable from general relativity only in the presence of relativistic pressure (or vorticity). Since the interior of neutron stars has high pressure and as their mass and radius can be measured observationally, they are the perfect laboratory for testing the validity of the aether...

We investigate new aspects related to the abelian gaugeHiggs model with the addition of the CarrollFieldJackiw term. We focus on oneloop quantum corrections to the photon and Higgs sectors due to spontaneous breaking of gauge symmetry and show that new finite and definite Lorentzbreaking terms are induced. Specifically in the gauge sector, a CPTeven aether term is induced. Besides, aspects of the oneloop renormalization of the background vector dependent terms are discussed.

This work concerns the loss of energy of a material system due to gravitational radiation in Einsteinaether theoryan alternative theory of gravity in which the metric couples to a dynamical, timelike, unitnorm vector field. Derived to lowest postNewtonian order are waveforms for the metric and vector fields far from a nearly Newtonian system and the rate of energy radiated by the system. The expressions depend on the quadrupole moment of the source, as in standard general relativity, but...

In this paper, second postNewtonian approximation of Einsteinaether theory is obtained by Chandrasekhar's approach. Five parameterized postNewtonian parameters in first postNewtonian approximation are presented after a time transformation and they are identical with previous works, in which $\gamma=1$, $\beta=1$ and two preferredframe parameters remain. Meanwhile, in second postNewtonian approximation, a parameter, which represents third order nonlinearity for gravity, is zero the same as...

In this paper, we describe the generation of the CPTeven, aetherlike terms via the new CPTeven magneticlike coupling. We carry out a study the loop corrections generated by this coupling. Previous investigations has been initiated on this issue and we have extended them to studying of higherpoint functions, of quantum corrections to vertices of the interaction and to twopoint function of the spinor field.

Based on the equivalence of the two different types of measurement protocols and the asymmetry between the Schr\"odinger and Heisenberg pictures, it has been previously proposed that negative sea fills the universe as a nondeterministic computation  a timereversal process of the irreversible computations presented since the big bang. The goal of this paper is to extend the proposed subjective universe model, i.e., the universe as a quantum measurement: Motivated by the relationship...

We extend the Einsteinaether theory to include the Maxwell field in a nontrivial manner by taking into account its interaction with the timelike unit vector field characterizing the aether. We also include a generic matter term. We present a model with a Lagrangian that includes crossterms linear and quadratic in the Maxwell tensor, linear and quadratic in the covariant derivative of the aether velocity fourvector, linear in its second covariant derivative and in the Riemann tensor. We...

We study a static, spherically symmetric and asymptotic flat spacetime, assuming the hypersurface orthogonal Einsteinaether theory with an ultraviolet modification motivated by the HoravaLifshitz theory, which is composed of the $z=2$ Lifshitz scaling terms such as scalar combinations of a threeRicci curvature and the acceleration of the aether field. For the case with the quartic term of the acceleration of the aether field, we obtain a twoparameter family of black hole solutions, which...

In this work we investigate the background dynamics when dark energy is coupled to dark matter with a suitable interaction in the universe described by EinsteinAether gravity. Dark energy in the form of Modified Chaplygin gas is considered. A suitable interaction between dark energy and dark matter is considered in order to at least alleviate (if not solve) the cosmic coincidence problem. The dynamical system of equations is solved numerically and a stable scaling solution is obtained. A...
